| 摘 要： | 静/慢地震是地壳能量释放的一种形式,可能消除一个正趋于断裂地带的地震威胁,也可能因为应力的转移而触发一个正常的地震;也有一些学者认为静/慢地震的发生并不在断层闭锁区域,两者的关系不大.对于静/慢地震的危险性尽管分歧较大,然而看法一致的是静/慢地震是地震断裂过程的一个组成部分,在地震成核作用中可能起着重要的作用,静/慢地...

| Abstract: | Silent/slow earthquakes are a form of crustal energy release,it is possible to eliminate the fracture of an earthquake fault but it is said that silent/slow earthquakes may also be the trigger of a normal earthquake because the stress transfer.Some scholars believe that the silent/slow earthquakes are not the fault latch area,little relationship between the two.Despite the divergence of viewpoint about the risk of silent/slow earthquake,there is a same view that the silent earthquake rupture process of slow... |
